"1 photo to download"
I have iCloud Photo Library turned on and syncing between my iMac, iPhone, and iPad. On the iPad only, the status message says "1 photo to download" but it never downloads. If I go to Photo settings on the iPad, it says the same thing, and if I make a change (like toggling Photo Stream on and off), it shows a progress bar and a little bit of activity before giving up.
Is there any way for me to find what this photo is that's choking on the iPad? I've tried scrolling through the thumb nails but I have over 16,000 photos and that's tiring. Don't really want to toggle iCloud Photo Library on/off with this many photos - takes too long to sync up.
Thanks for any help/info.
iPad Air, iOS 8.3
